[0064] [air conditioner]

[0065] In some embodiments of the present application, an air conditioner is provided, which performs a refrigeration cycle of the air conditioner by using a compressor, a condenser, an expansion valve and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion and evaporation, and refrigeration or heating of indoor space.

[0066] The low-temperature and low-pressure refrigerant enters the compressor, which compresses the refrigerant gas into a high-temperature and high-pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.

[0067] The expansion valve expands the high-temperature and high-pressure liquid-phase refrigerant formed in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a refrigeration effect by exchanging heat with the material to be cooled using the latent heat of evaporation of the refrigerant. Throughout the cycle, the air conditioner can adjust the temperature of the indoor space.

[0068] The outdoor unit of the air conditioner refers to the part of the refrigeration cycle including the compressor and the outdoor heat exchanger, the indoor unit of the air conditioner includes the indoor heat exchanger, and the expansion valve can be provided in the indoor unit or the outdoor unit.

[0069] The indoor heat exchanger and the outdoor heat exchanger are used as a condenser or an evaporator. When the indoor heat exchanger is used as a condenser, the air conditioner is used as a heater in a heating mode, and when the indoor heat exchanger is used as an evaporator, the air conditioner is used as a cooler in a cooling mode.

[0070] [Outdoor unit]

[0071] In some embodiments of the present application, Figure 1 is a structural diagram of an outdoor unit, Figure 2 is a structural diagram of an outdoor unit after omitting the external grille 20, Figure 3 is an exploded view of an outdoor unit. The outdoor unit includes a machine housing 10, and the machine housing 10 is provided with an air outlet 110 and an air return. For example, the front side of the machine housing 10 is provided with the air outlet 110, and the rear side of the machine housing 10 is provided with the air return.

[0072] The outdoor unit includes a partition plate that divides the inner cavity of the outdoor unit into a first inner cavity and a second inner cavity. The air return, the air outlet 110, and the first inner cavity are in communication. The second inner cavity is provided with a compressor and an electrical box.

[0073] The outdoor unit further includes a heat exchanger. The heat exchanger is arranged in the first inner cavity of the machine housing 10, and the heat exchanger is configured to exchange heat with the air flowing through it.

[0074] The outdoor unit further includes a fan 30. The fan 30 is arranged in the first inner cavity of the machine housing 10, and the fan 30 is configured to provide air flow power.

[0075] Under the action of the fan 30, external air flows into the machine housing 10 through the air return, flows through the heat exchanger to exchange heat, and the heat-exchanged air is discharged from the air outlet 110.

[0076] The shell 10 comprises a front panel 100. The front panel 100 is provided with an air outlet 110, and covers the front side of the first inner cavity.

[0077] The shell 10 further comprises a maintenance panel 200. The maintenance panel 200 covers the front side of the second inner cavity. The maintenance panel 200 is detachable, so that the compressor, the electrical box and other components in the second inner cavity can be maintained.

[0078] The front panel 100 and the maintenance panel 200 jointly constitute the front panel of the shell 10.

[0079] [Grille]

[0080] The outdoor unit further comprises a grille 20 configured to cover the front panel 100 and the maintenance panel 200. The grille 20 is provided with a ventilation gap for gas flow, and the ventilation gap is in communication with the air outlet 110.

[0081] In other words, the grille 20 not only covers the air outlet 110, but also covers the entire front panel of the shell 10, that is, the grille 20 covers the entire front view of the outdoor unit, and the grille 20 constitutes the main visual surface of the outdoor unit, breaks the image of the outdoor unit with a "large air hole" in the conventional technology, forms the differentiated design of the product, and provides a brand-new visual effect for the user.

[0082] The front panel 100 and the maintenance panel 200 have a joint gap, denoted as a second joint gap 42, which is visually obvious and affects the visual effect of the entire machine. Water is prone to seep at the second joint gap 42, and external water seeps into the interior of the machine through the second joint gap 42, reducing the reliability of the product.

[0083] Since the grille 20 covers the entire front view of the outdoor unit, that is, the grille 20 covers the second joint gap 42, the risk of water seepage at the second joint gap 42 is reduced.

[0084] In some embodiments of the present application, the grille 20 is made of PP material, which is easy to process and low in cost.

[0085] In some embodiments of the present application, the grille 20 is detachably arranged on the front panel 100 and the maintenance panel 200. The grille 20 is detachable, so as not to affect the disassembly of the internal front panel 100 and the maintenance panel 200, and facilitate the internal maintenance of the machine.

[0086] In some embodiments of the present application, with reference to Figure 2 , the shell 10 further comprises a top plate 12, and the first joint gap 41 is arranged between the front panel 100 and the top plate 12 and between the maintenance panel 200 and the top plate 12.

[0087] With reference to Figure 6The grid 20 includes a top turn-up portion 21 provided at the top of the grid 20. The top turn-up portion 21 extends, for example, horizontally, towards the direction of the casing 10. The top turn-up portion 21 is configured to cover the first joint 41.

[0088] Covering the first joint 41 at the top by the top turn-up portion 21 helps to reduce the risk of rain seepage at the first joint 41 and improve the visual consistency of the front visual subjective surface of the outdoor unit.

[0089] In some embodiments of the present application, the grid 20 includes a rib 25 located on the side of the grid 20 away from the casing 10. The grid 20 is provided with an opening (not labeled) corresponding to the air outlet 110, and the rib 25 covers at least the opening. The rib 25 meets the test requirements, and at the same time, the rib 25 also serves as the appearance decoration surface of the grid 20.

[0090] [First sub-grid]

[0091] In some embodiments of the present application, the grid 20 includes a first sub-grid 300. Figure 10 A structural view of the first sub-grid 300 viewed from the air outlet side, Figure 12 A structural view of the first sub-grid 300 viewed from the air inlet side.

[0092] Referring to Figure 3 The first sub-grid 300 is provided on the front panel 100 and is configured to cover the front panel 100. The first sub-grid 300 is provided with a ventilation gap, and the air flowing out of the air outlet 110 is discharged through the ventilation gap.

[0093] The front panel 100 is of a rectangular structure, and correspondingly, the first sub-grid 300 is also of a rectangular structure. The first sub-grid 300 not only covers the air outlet 110, but also covers the entire front panel 100, and the front panel 100 is not exposed. The first sub-grid 300 constitutes part of the front visual subjective surface of the outdoor unit.

[0094] The first sub-grid 300 is provided on the front panel 100 rather than at the air outlet 110, the distance between the first sub-grid 300 and the internal fan 30 is increased, and the rib on the first sub-grid 300 extends a certain distance in the air outlet direction, thereby achieving the effect that the fan 30 is not visible from the front of the machine.

[0095] Since the rib on the first sub-grid 300 extends a certain distance in the air outlet direction, it has a good flow guiding effect on the air outlet, which helps to increase the air supply distance.

[0096] The ventilation area of the first sub-grating 300 is larger than the area of the air outlet 110, so that the air flowing out of the air outlet 110 can flow out of the first sub-grating 300 with a larger ventilation area, which helps to increase the air volume.

[0097] In some embodiments of the present application, with reference to Figure 10 and Figure 12 The first sub-grating 300 includes a frame 310, which constitutes a frame structure of the first sub-grating 300. The frame 310 is configured to be connected with the front panel 100 to achieve fixed installation of the first sub-grating 300 on the front panel 100. The frame 310 surrounds an opening that is in communication with the air outlet 110.

[0098] The first sub-grating 300 further includes a plurality of ribs 25 connected with the frame 310. The plurality of ribs 25 are configured to cover the opening, and ventilation gaps are formed between adjacent two ribs 25.

[0099] In other words, the area of the opening is larger than the area of the air outlet 110, which helps to increase the air volume. The frame 310 constitutes the frame structure of the first sub-grating 300, and the ribs 25 are formed on the frame 310. The plurality of ribs 25 not only form ventilation gaps, but also play a decorative role on the appearance surface of the grating 20.

[0100] In some embodiments of the present application, the ribs 25 include a plurality of first ribs 320 arranged at intervals and a plurality of second ribs 330 arranged at intervals. The first ribs 320 are referred to as first horizontal ribs, and the second ribs 330 are referred to as first vertical ribs. The first ribs 320 and the second ribs 330 extend in different directions, and the first ribs 320 intersect with the second ribs 330.

[0101] For example, the first ribs 320 extend in the left-right width direction of the casing 10, and the second ribs 330 extend in the up-down height direction of the casing 10. The first ribs 320 intersect with the second ribs 330, which improves the structural strength of the first sub-grating 300.

[0102] [Second sub-grating]

[0103] In some embodiments of the present application, the grating 20 further includes a second sub-grating 400. Figure 16 A structural view of the second sub-grating 400 viewed from the air outlet side, Figure 17 A structural view of the second sub-grating 400 viewed from the air inlet side. The second sub-grating 400 is arranged on the maintenance panel 200, and the second sub-grating 400 is configured to cover the maintenance panel 200.

[0104] In other words, the maintenance plate 200 is in a rectangular structure, and the second sub-grating 400 is also in a rectangular structure. The second sub-grating 400 covers the entire maintenance plate 200, and the maintenance plate 200 is not exposed. The second sub-grating 400 constitutes a part of the front visual subjective surface of the outdoor unit.

[0105] In some embodiments of the present application, the second sub-grating 400 includes a base body 410, which is in a plate structure. The base body 410 is provided with a plurality of reinforcing ribs on the side facing the cabinet 10, so as to improve the structural strength of the second sub-grating 400.

[0106] The base body 410 is provided with a plurality of ribs on the side away from the cabinet 10. For example, the second sub-grating 400 is provided with a plurality of third ribs 420 and a plurality of fourth ribs 430 arranged at intervals on the side away from the cabinet 10. The third ribs 420 are referred to as second horizontal ribs, and the fourth ribs 430 are referred to as second vertical ribs. The extending directions of the third ribs 420 and the fourth ribs 430 are different, and the first ribs 320 and the second ribs 330 intersect.

[0107] For example, the third ribs 420 extend along the left-right width direction of the cabinet 10, and the fourth ribs 430 extend along the up-down height direction of the cabinet 10. The third ribs 420 and the fourth ribs 430 intersect, thereby improving the structural strength of the second sub-grating 400.

[0108] The plurality of first ribs 320 and the plurality of third ribs 420 are in one-to-one butt joint, and the spacing between adjacent ribs is consistent. In this way, after the first sub-grating 300 and the second sub-grating 400 are installed in place, they constitute an overall appearance consistent whole, and form an entire grating structure on the front visual subjective surface of the outdoor unit.

[0109] [Mounting structure between grating and cabinet]

[0110] In some embodiments of the present application, the connection structure between the first sub-grating 300 and the front panel 100 and the connection structure between the second sub-grating 400 and the maintenance plate 200 are the same, both of which are in a combination of clamping and screws, facilitating disassembly and assembly.

[0111] With reference to Figure 2 , the front panel 100 and the maintenance plate 200 are provided with first clamping parts 510 and first fixing positions 610, for example, the first fixing positions 610 are screw holes.

[0112] With reference to Figure 8 , the first sub-grating 300 and the second sub-grating 400 are provided with second clamping parts 520 on the side facing the cabinet 10. The first sub-grating 300 and the second sub-grating 400 are also provided with second fixing positions 620, for example, the second fixing positions 620 are screw posts, and the screw posts are provided with through screw holes.

[0113] The first clamping part 510 is clamped with the second clamping part 520, and the first fixing position 610 is connected with the second fixing position 620 through a connecting piece, for example, the connecting piece is a screw.

[0114] During installation, the first clamping part 510 is clamped with the second clamping part 520 first, and then the first fixing position 610 is fixed with the second fixing position 620 through a screw, so that the fixed installation between the grid 20 and the cabinet 10 is realized. The clamping plays a role of installation positioning, and the final locking and fixing are realized through the screw, and the structure is reliable.

[0115] In some embodiments of the present application, referring to Figure 8 , the grid 20 is provided with a plurality of second clamping parts 520 arranged at intervals at the position close to the top, and the left and right sides and the bottom side of the grid 20 are provided with a plurality of second fixing positions 620.

[0116] During installation, the first sub-grid 300 and the second sub-grid 400 are respectively installed independently, and the installation processes of the two are the same. First, the first clamping part 510 and the second clamping part 520 at the top are clamped, and then the grid 20 is hung on the cabinet 10, and finally the locking and fixing are realized through a screw, so that the installation is facilitated.

[0117] In some embodiments of the present application, referring to Figure 2 , the first clamping part 510 is a clamping hole 511 formed on the front panel 100 and the maintenance plate 200, which is convenient for processing. Figure 19 is a structure diagram of the clamping hole 511. The second clamping part 520 is a clamping hook 521 formed on the grid 20, Figure 13 is a structure diagram of the clamping hook 521. The clamping hook 521 is clamped in the clamping hole 511.

[0118] In some embodiments of the present application, referring to Figure 19 , the clamping hole 511 includes a communicating clamping hole first section 512 and a clamping hole second section 513, the clamping hole first section 512 is located above the clamping hole second section 513, along the width direction of the front panel 100, that is, along the width direction of the cabinet 10, the width of the clamping hole first section 512 is greater than the width of the clamping hole second section 513. In other words, the clamping hole 511 is an opening structure with wide top and narrow bottom.

[0119] The clamping hook 521 is clamped by the first clamping hole section 512 to the second clamping hole section 513. The first clamping hole section 512 with a wider width facilitates the insertion of the clamping hook 521. The second clamping hole section 513 with a narrower width helps to improve the clamping stability of the clamping hook 521 and avoid left and right shaking after clamping.

[0120] In some embodiments of the present application, referring to Figure 13 The clamping hook 521 includes a clamping hook horizontal part 522 and a clamping hook vertical part 523. The clamping hook horizontal part 522 extends from the grid 20 to the direction close to the shell 10. The clamping hook vertical part 523 extends downward from the clamping hook horizontal part 522. The clamping hook horizontal part 522 and the clamping hook vertical part 523 form a gap 524. The bottom side edge of the clamping hole 511 is inserted into the gap 524. The clamping between the gap 524 and the clamping hole 511 helps to improve the insertion reliability and avoid front and back shaking after clamping.

[0121] In some embodiments of the present application, the outer end surface of the connecting member (such as a screw) is not higher than the outer surface of the grid 20. In other words, the outer surface of the grid 20 is the outer surface of the rib 25. The outer end surface of the connecting member is not higher than the outer end surface of the rib 25, which means that the connecting member (such as a screw) is embedded in the rib 25, and the rib 25 is used to hide the connecting member.

[0122] In some embodiments of the present application, referring to Figure 14 In the air outlet direction of the outdoor unit, the width of the first rib 320 is greater than the width of the second rib 330. The second fixed position 620 penetrates the first rib 320. The outer end surface of the connecting member is not higher than the outer end surface of the first rib 320.

[0123] In other words, the first rib 320 extends a certain distance in the air outlet direction, which has a good hiding effect on the internal fan 30 and achieves the effect that the fan 30 is invisible from the front side of the outdoor unit.

[0124] The second fixed position 620 penetrates the first rib 320, which hides the screw in the second fixed position 620 and realizes the hidden design of the screw. In other words, the screw is hidden by the higher rib 25, and the screw can be well hidden due to the reflection of light at the shape change.

[0125] In some embodiments of the present application, referring to Figure 8 The first sub-grid 300 and the second sub-grid 400 are provided with an extension rib, which abuts against at least one of the front panel 100 and the maintenance panel 200 to prevent the air flowing out of the air outlet 110 from flowing to the second sub-grid 400.

[0126] For example, referring to Figure 12The first sub-grating 300 is provided with a first extending rib 360 extending along the height direction of the shell 10, and the first extending rib 360 abuts against the front panel 100. Figure 17 The second sub-grating 400 is provided with a second extending rib 460 extending along the height direction of the shell 10, and the second extending rib 460 abuts against the maintenance panel 200.

[0127] The abutting design plays a blocking role on the air flowing out of the air outlet 110, avoids the air flowing to the second sub-grating 400, and thus makes the air flow out of the first sub-grating 300.

[0128] In some embodiments of the present application, referring to Figure 2 The front surface of the shell 10 is provided with a first arc surface 11 at a position close to the side surface of the shell 10, and the first arc surface 11 extends along the height direction of the shell 10.

[0129] Referring to Figure 7 and Figure 8 The grating 20 further comprises a side turning edge portion 22 extending along the height direction of the shell 10, and the side turning edge portion 22 abuts against the shell 10. The grating 20 further comprises a bottom turning edge portion 23 extending along the width direction of the shell 10.

[0130] The bottom of the side turning edge portion 22 is connected to the end of the side turning edge portion 22, the bottom turning edge portion 23 is provided with a second arc surface 24, and the second arc surface 24 is adapted to abut against the first arc surface 11. In this way, the grating 20 and the shell 10 are better abutted.
